Yet that's just what happened this past weekend for some customers flying on British discounters Flybe and easyJet. The Daily Express newspaper reports: Prince William, the Duchess of Cambridge and Prince Harry flew to and from Edinburgh on budget airlines for their cousin Zara Phillips's wedding to England rugby star Mike Tindall last weekend. William and Kate, both 29, and Harry, 26, each paid for their own flights.William and Kate flew to Edinburgh on discount carrier Flybe. The couple flew out of Manchester, which is the nearest big airport to their North Wales home, according to the Daily Express. Flybe's fares on the route begin at about $59 each, according to the newspaper.
